2 Claims.

This invention relates to closure fastener devices, or what might also be termed clamp fasteners. More particularly, the invention relates to devices of this kind whereby a cover, lid and the like may be quickly mounted in position and quickly released for removal, while at the same time providing a fastener which will tensionally .retain the cover or lid in closed position and against accidental removal. Still further, the invention relates to a fastening device wherein one of the members of the device comprises a part on or secured to the cover or lid, and shaped to form a portion of a hinge coupling wherein the other part has a corresponding hinge portion with means for mounting and retaining a hinge pin or pintle in a simple and eflicient manner, while maintaining the pintle against displacement from said parts.

The novel features of the invention will be best understood from the following descriptions when taken together with the accompanying drawing,

in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 is a plan view diagrammatically illustrating a container with two fastening devices arranged thereon.

Fig. 2 is a partial section on the line 2-2 of Fig. 1 on an enlarged scale.

Fig. 3 is a view looking in the direction of the arrow 3 of Fig. 2, showing part of the construction broken awa and in section; and

Fig. 4 is a section on the line 4-4 of Fig. 2, but illustrating the parts in a partially assembled position, and detached.

In various types of containers, it is desirable to provide means for quickly removing a cover or lid of the container, and for such purposes. we have devised a closure or clamping device, which, in addition to fulfilling the requirement of quick attachment and detachment of the cover or lid,

also has the property of maintaining the cover or lid in tensional engagement with the container so as to provide at all times, a tight closure for the Further, we provide a device of the kind described wherein the separate parts of the device are retained against displacement from the container and cover.

The invention is particularly adaptable for use in retaining covers on wooden containers used for the-transportation of various types and kinds of war equipment, and particularly such things as ammunition, where it is desirable to have a means for quickly removing the cover to gain access to the ammunition stored in the container. In such uses; it is alsoesential that the fastener or clamping device will maintain the cover in tight engagement with the container and against accidental displacement regardless of the rough handling to which the container may be subjected.

In illustrating one adaptation of the invention, a container of the kind last referred to is illustrated diagrammatically at 5, in Fig. l of the drawing, and comprises an elongated wooden box reinforced at the end corners by strips 6, which, as will appearfrom a consideration of Fig. 2 of the drawing, have ends I which protrude above the upper edge8 of the box 5, so as to engage end walls 9 of a cover or lid 19. These reinforcing strips 6 thus retain the cover I0 against endwise or longitudinal movement with respect to the box, whereasthe fastener or clamping devices i I retain the cover In against transverse movement with respect to the box.

Each device comprises two members, one secured to the container or box, and the other to the cover. As both devices I l are of the same construction, the brief description of one will be applied to both. In the construction shown, onemember comprises, a catch part 92, which is secured to the end wall of the box 5, by suitable fastenings I3. This part has an outwardly curved arm portion I l, which has spring properties, and this arm terminatesin a cylindrical catch end l5. The part I2 is made from a strip of material of the samewidth throughout its length, as will clearly appear from a consideration of Fig. 3 of.

the drawing.

The other member of the device. in the construction shown, is composed of two parts 16 and H. The part It has a dove tailed plate l8, preferably-countersunk in the upper surface of the cover H], as seen in Fig. 2, and secured to the cover by screws or other fasteners [9. The part It; includes an angularly extending portion 20, which extends over the end wall of the cover 10, and this end terminates in spaced cylindrical pintle bearings 2| and laterally extending rounded ears 22, note Fig. 4 of the drawing. This particular description of the part [6 is in the initial blanking and shaping position thereof, and before assemblage with the part ll. After assemblage, as will later be described, the ears 22 extend outwardly and in parallel relation to each other, as will appear in Figs. 1 to 3 inclusive. The central portion of the angular end 20 is cut out, as seen at 23, and this serves to space the bearings 2|.

The member l6 comprises an elongated strip of material for the most part preferably of the same width as the strip from which the member I2 is formed. The part i! is preferably bowed outwardly to a slight extent to give spring properties thereto, as will clearly appear in Fig. 2 of the drawing. One end of the part I! has an inwardly directed angular plate portion 24,.which terminates in a cylindrical projection 25 exposed on the inner surface of the plate portion 24, and in such position with respect to the pivot mounting of the part II, later described, as to frictionally and tensionally .pass over the cylindrical end l of the catch l2. an acute angle with respect to the body portion of the part II, to form a finger piece portion shaped to form a cylindrical bearing 26 centrally thereof and corresponding generally in diameter to the bearings 2|, and adapted to fit snugly between said bearings. Mounted in the bearings 26 and 2| is a hinge pin or pintle 21, thus providing a hinge mounting of the part 17 in connection with the part Hi. The pintle 21 is equal to or slightly less than the combined length of the bearings 2!, 26, and is retained in position and against displacement by the ears 22, which overlie the outer ends of the bearings 2!,

In constructing and assembling the parts l6 and H, the part It is produced with the cars 22 left in what might be termed the blanked form, that is to say, extending laterally and in the manner illustrated in Fig. 4 of the drawing, thus it becomes a very simple matter to hingedly couple the parts It and I l by simply alining the bearings 2|, 26, placing the pintle 21 in said bearings and then folding the ears 22 from the full line position of Fig. 4, into the dotted line position of said figure, which latter position is the full line position of the ears, as appearing in Figs. 1 to 3 inclusive.

In this present application the uniting of the parts I6 and I1 is materially simplified from a production standpoint over the teachings in prior application 493,001, filed July' 1, 1943, and furthermore, a strong and durable pivot or hinge mounting of the part I1 in connection with the part I6 is provided, and one in which a freer swinging movement of the part I! is provided. Still further, a definite pivot point of swinging movement of the part I! is maintained so as to govern and control positioning of the cylindrical projection 25 with respect to the cylindrical catch end [5 of the catch device. In this way, a more positive control can be had of the degree of tensional engagement of the cover with the container.

It will be understood that the invention is not limited to the specific arrangement of the parts as herein illustrated, nor on containers of the kind described in defining one use of the invention. Furthermore, the particular material em- The plate portion 24 extends atand pintle 21 with the end closures 22 on the bearings 2| produces what we would term a floating pintle mounting, particularly in usin a pintle pin slightly shorter than the over all dimensions of the bearing collectively. The term floating, as here used, is in the sens that the pintle is free to rotate, as well as to have endwise movement. This will provide free shifting of the pintle in the bearings and a better distribution of wear on the bearings and pin.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In fastener devices of the class described, a member comprising two parts having a permanent hinge connection, the permanent connection of said parts comprising interfitting cylindrical bearings, a pintle pin shorter than the over-all length of the interfitting bearings of said parts to provide free endwise and rotary movement of the pin in said bearings, means integral with one of said parts closing the ends of said bearings and limiting endw'ise movement of the pin therein, one part comprising a mounting plate, the other part comprising an outwardly bowed arm, and the free end portion of said arm having an integral wall disposed at an acute angle with respect to the inner surface of said arm, said wall terminating in a cylindrical end spaced from said inner surface of the arm and adapted for engagement with a yieldable catch.

2. In fastener devices of the class described, a member comprising two parts, one part of said member having spaced cylindrical pintle bearings, the other part comprising an elongated outwardly bowed arm, one end of said arm having a pintle bearing arranged between and registering with the hearings or the first part, a pintle couplin said bearings to provide free swinging movement of the arm on the first part, the other end of arm having a short inturned wall portion forming a substantially V-shaped fingerpiece protruding at said end of the arm, and said short wall portion terminating in a cylindrical member arranged in spaced relation to said arm and adapted to engage a yieldable catch.
